Generally, after the flameout of the vehicle, the higher frequency of using the car, the higher frequency of replacing the battery. Therefore, people often ask: Can lithium batteries be used instead of lead-acid batteries for car starter batteries?

The electric vehicle battery stayed idle at home for a month,Why only half of power is left?Is it your own misuse? Or is there something wrong with the quality of the battery itself?

How to use and maintain the battery of electric vehicle has always been a topic of concern. "Do I need to charge the battery I just bought?" "How to maintain?" "Do batteries need to be charged after being placed for a long time?", this article will share you some common problems of electric vehicle battery maintenance, hope it can help you after reading.

The failure of lead acid batteries is the result of many factors, which is determined by the internal factors of the plate, such as the composition of active substances. Crystal form, porosity, plate size, grid material and structure also depend on a series of external factors, such as discharge current density, electrolyte concentration and temperature, discharge depth, maintenance status and storage time. Here are the main external factors.

the phenomenon that the active material on the battery plates are gradually turned into lead sulfate with coarse and hard crystals full of plate surface due to deep discharge (too much) or long-term insufficient charge, which will block the plates micropore and hinder the electrolyte penetration and conduction current, thus the battery charging and discharging performance is extremely deteriorated, and the actual capacity is seriously insufficient; and it could not be reduced to lead dioxide and spongy lead by conventional charging methods.

Lead acid battery is mainly composed of positive/negative plate group, separator, battery container, electrolyte, battery cover, etc. The electrode is mainly made of lead and lead oxide, and the electrolyte is sulfuric acid solution.

Do you know how to group the batteries? Do you know how to calculate the driving mileage of electric vehicles batteries? Do you know how to add repair fluid to the battery? If you don't know, you must read this article.

However, the above phenomenon is not common, and most chargers will not or do not often have similar problems. This kind of charger is not only rare, but also a relatively old one that has been used for many years. The correct way to use the charger is that at the later stage of charging, although most of it has been charged, a small amount of sulfurized substances on the plate are not completely reduced.

If battery overheating is caused by excessive discharge current, there may be the following reasons:

Power batteries include lithium-ion power batteries, metal hydride/nickel power batteries, etc. Lithium-ion power batteries are usually referred to as lithium-ion batteries. Lithium-ion batteries are an important category of power lithium batteries for new energy vehicles and have the largest market share.

Sometimes, my friend will ask me a question: my car's battery has been used for 3 to 4 years, except for the dust in the corner, the appearance looks good, it is almost new. But all of a sudden it broke down. What happened?

What are the differences between power lithium batteries and ordinary 18650 lithium batteries?
